Patented May 19, 1925.

JOHN "V. BUTTS, OF SN".DERS`KENTUCKY.

WRENCH;

Application fled March 18, 1924. Serial No. 700,116.

To all whom z'tmay concern:

Be it known that I, JOHN V. BUTTS, a citizen of the United States,residing at Sanders, in the county of Carroll and State of Kentucky,have invented new and useful Improvements in Wrenches, of which thefollowing is a specification.

This invention relates to wrenches and has for an object the provisionof a wrench of simple and durable construction which is capable of rapidadjustment and which will be securely held in adjusted position.

More specifically stated, the invention provides a wrench which includesa rigid jaw and a relatively movable jaw which is adjustable upon theshank of the rigid jaw, with means carried by the movable jaw wherebythe latter may be adjusted and held in adjusted position, the raid meansincluding an inner sleeve which carries the movable jaw and an outersleeve which may be operated to hold the movable jaw in adjustedposition, the holding means also acting to retain the outer sleeve uponthe inner' sleeve.

Vith the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

Figure 1 is an elevation of a wrench constructed in accordance with theinvention.

Figure 2 is an edge view of the same.

Figure 3 is an elevation looking at the reverse side from that shown inFigure 1.

Figure 4 is a transverse section on the line 4-4 of Figure 2.

Figure is a detail section taken diametrically through the outer sleeve.

Referring to the drawings in detail, the reference character indicatesthe shank of the improved wrench which is provided at one end with ahandle or grip 11 and at its r opposite end with a jaw 12 which is rigidwith the shank. The opposite sides of the shank are longitudinallyrecessed as shown at 18, the recess upon one side of the shank openinginto one edge, while the recess upon the opposite side of the shankopens into the opposite edge so that the said recesses are relativelyoffset. Extending from opposite sides of the shank are spacedprojections or teeth 14, the latter extending from the ,inner to as theinner sleeve, the said sleeve having extending from one end thereof ajaw 16. The sleeve 15 is mounted for sliding movement along the shankand for this purpose is provided with grooves 17 which receive oppositeedges of said shank and by sliding the sleeve, the jaw 16 may beadjusted with respect to the jaw 12, as will be readily understood.

Rotatably mounted upon the inner sleevey 15 is an outer sleeve 18 whoseouter periphery is preferably knurled or serrated as shown. This outersleeve carries inwardly extending oppositely disposed vprojections orlugs 19 which are adapted to pass through openings or slots 2O providedin the inner sleeve 15, upon diametrically opposite sides thereof. Thelugs 19 are adapted to engage the spaced teeth 14 to hold the movablejaw 16 in adjusted position. By rotating the outer sleeve 18, the lugs19 may be disengaged from the teeth 14 and rapid adjustment of themovable jaw effected.

rlhe outer periphery of the inner sleeve 15 is provided with oppositelydisposed spaced recesses 21, while secured within the outer 'sleeve 1Sare oppositely located spring arms or fingers 22 which are provided withoffset portions for engagement with the walls of the notches 21. Thenotches are so spaced as to receive the offset portion of the spring 22when the movable jaw 16 is in either locked or released position so thatthe sleeve 18 will be held against accidental rotation.

rI he invention is susceptible of various changes in its form,proportions and minor details of construction andthe right is hereinreserved to make such changes as properly fall within the scope of' theappended claim.

Having described the invention what is claimed is A wrench comprising ashank having longitudinally disposed relatively offset recesses. inopposite sides thereof, rows of spaced teeth extending downwardly andlongitualsA dinally With the shank from opposite sides Voppositelydisposed lugs received in the 0f an integral jaw adjacent the recesses,a slots and interposed between the teeth, and 10 transversely slottedinner sleeve having spring means included in the rotatable sleeveopposed guide grooves and sldngly recevfor engagement Withthe innersleeve to hold ing the opposite edges of the shank therein, the sameagainst accldental displacement.
